Archaeologists have long used carbon-14 dating (also known as radiocarbon dating) to estimate the age of certain objects.Traditional radiocarbon dating is applied to organic remains between 500 and 50,000 years old and exploits the fact that trace amounts of radioactive carbon are found in the natural environment.The researchers found that year-of-death determinations based on nails were accurate to within three years.The generally poor post-mortem preservation of soft tissues would be a limiting factor to this approach.

The older beta counting instrument was stretched to get results of 50,000 years, whereas the AMS instrument should be effective up to 95,000 years.

Unlike tooth enamel, soft tissues are constantly being made and remade during life.

Thus, their radiocarbon levels mirror those in the changing environment.

The researchers wanted to find out if they could identify a person's year of birth or year of death using precise measurements of carbon-14 levels in different post-mortem tissues.

They measured carbon-14 levels in various tissues from 36 humans whose birth and death dates were known.

It is confusing when the maximum date for Carbon 14 is listed as 60,000 years and 80,000 years in the same article (Chapter 4 Dating Methods by Roger Patterson and the reference article summary 4.2 by Riddle.) and as 50,000 years in another (The Answers Book) as well as 95,000 years in the Creation College lecture by Dr. This is why there is the disparity in the quoted limits to radiocarbon dating, as highlighted by this inquirer.
